XSLT 속성 값이 다른 경우 노드 결합

Question

변환하는 동안 하나의 노드를 다른 노드로 결합 할 수있는 사람. 예를 들어, Attributes/Attribute/Type = ComplexAttr 일 때 Attributes/Attribute/Type = Common에만 있어야합니다. 다음은 사용하려는 XML & XSLT 샘플이 작동하지 않는 것입니다. TIA (미리 감사드립니다)

<?xml version="1.0" encoding="utf-8"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

     </Data> 
    </xsl:template> 
    <xsl:template 
      match="Attribute[generate-id()=generate-id(key('type', Type)[1])]">

       <xsl:if test="Type = 'ComplexAttr'"> 
        <xsl:value-of select="Common"/> 
       </xsl:if> 
       <xsl:apply-templates select="../Attribute[Type=current()/Type]" mode="out"/>

같은 그룹에 Type과 'common' 및 'ComplexAttr'을 입력하면 키 값 표현식을 다음과 같이 변경해야합니다.

적용 및 그룹 템플릿 : (210)

<xsl:key name="type" 
     match="Attribute" 
     use="concat(
       Type[. != 'ComplexAttr'], 
       substring(
        'common', 
        1 div (Type = 'ComplexAttr') 
       ) 
      )"/> 

<xsl:template match="Attribute[ 
         generate-id() 
         = generate-id(
           key('type', 
            concat(
            Type[. != 'ComplexAttr'], 
            substring(
             'common', 
             1 div (Type = 'ComplexAttr') 
            ) 
           ) 
          )[1] 
          ) 
        ]">  

편집

<xsl:apply-templates select="key('type', 
           concat(
            Type[. != 'ComplexAttr'], 
            substring(
             'common', 
             1 div (Type = 'ComplexAttr') 
            ) 
           ) 
          )" 
        mode="out"/> 

편집 : 전체 예. 이 스타일은 :
